They do burn longer. I got 35 seconds on a couple of them (normal ones are gone in about 15 seconds). Dipping them in water can put the flame on "hold" for a little while and extend the time. They are large, but no problem for a backpack.
Thanks Montanero! When my frozen fingers couldn't work a BIC a few years ago, stormproof matches were worth their weight in gold, and earned a place in my pack. If you need them for last ditch, the longer burning the better!
The Titan matches do burn a loooong time! I'm not sure if they're worth the extra money. I mean, they work as advertised but you could simply carry more of the smaller ones for the same amount of space and price. Still they're a very impressive product.
But then again..... you guys makes it hard to pick gear sometimes. LOL!
